I built 5.18.1 with gcl-2.6.8pre sans `batch' patch, and I had no
make_writable errors during `make check', too.
However, I have a script that behaves quite oddly with this maxima:
-When invoked in maxima via load("foo.mac"), the make_writable error appears
predictably after about 5 minutes.
-When the script is run from the command line via `maxima -b foo.mac' the
script runs fine.
(It has been running for about 18hours at the moment, and I expect it'll run for
10+days, barring further errors).
